To all whom it may canoe/"It:

15e-- it known that 1, EDGAR l lla'rnawnr, .a c-itiien of the United States, and a resident of Wellesley, in the county 01 Norfolk and State of Massachusetts, have invented an Improvement in Textile Machines, of which the following description, in connection. \vitlrtlie accompanying drawings, is a. speci lication, like characters on the drawings representing like parts.

This invention relates to textile machines, being more particularly concerned with machines for selecting and separating warp threads and presenting them successively to the action of some mechanism, such, for example, as a thread placing device or member. For purposes of illustration, the invention is herein shown embodied in a warp drawing or thread placing machine where the thread placing device is utilized for placing the warp threads through drop wires, harness eyes and reed dents. While my invention has particularly advantageous application for a machine of this class, it

15, however, susceptible of broad application to machines intended for other or similar purposes than drawing-in machines wherein the selection and separation of warp or other threads is required.

The character of the invention will be best understood by reference to the following description ofan illustrative embodiment thereof, shown in the accompanying drawing, whcrein I Fig. 1 is an end elevation of a warp drawing machine constituting the preferred embodiment of my invention;

Fig. 2 is a front elevation of the left hand end of said machine;

Fig. 3 is a front elevation of the right hand end thereof;

Fig. 4 is a view partially in plan and partially in horizontal section upon the line -1-4 of Fig. 1, of the left hand end of the machine; 5

Fig. 5 is a similar view of the right hand end of the machine;

Fig. 6 is a detail, partially in end elevation and partially in vertical section, on an enlarged :scale, of the means for driving the warp supports or carriages;

Fig. 7 1s a detail in end elevation of a portion of the means for driving the warp supports or carriages;

Fig. 8 is a front elevation of the construction shown in Fig. 7;

Fig. 9 is a detail in vertical section on the line 99 of Fig. 6;

Fig, 10 is a plan view of the pattern mechanism and the driving connections for certain of the parts, including the releasing keys, the drop wire feed worms, and the continuous driving means for the warp worms; and

Fig. ii is a view in section on the line I.l1l of FigIlO.

While the invention in many of its aspects is applicable to machines other than warp drawing machines and also to warp drawing machines of other types and constructions than that herein shown, I have herein illustrated the invention by embodiment in a well known type. of drawing-in machine, which therefore need not be described in entire detail.

The machine here shown may,'as to certain features thereof, be of the same general construction as the type of machine shown in British Patent N 0. 1,661 of 1904 and the United States Patent to Charles Lea, No.

1,153,869, dated September 14, 1915.

In the illustrated form of machine, as is well known to those skilled in the art, the

heddles, warp threads and drop wires or other similar loom elements which may he and preferably are employed, are supported in a general parallel arrangement lengthwise the machine upon suitable supports carried by the main frame 1 of the machine Any suitable thread placing device is provided. I have herein represented a drawing needle 2 adapted to be suitably rcciprocated and carried by the traveling carriage 3, shown most clearly in Fig. The said carriage with its needle is caused to traverse the extent of the reed which is or may be supported in the usual manner and is not herein indicated, and the extent of the heddles, which likewise have been omitted to permit clea' -ness of illustration of other parts. The drawing needle is also traversed the extent of the drop wires if the latter be emplo ed, such drop wires being of any suitab e construction, not herein necessary to disclose, and being similar if desired to thoseindicated in the copending applica- 17, 1914 (now Patent tion of Edward La Chance and Joseph Pennell, Serial No. 877,769, filed December No. 1,317,024, dated September 23, 1919).

The needle carriage 3 is positively traversed through the machine by means hereinafter described, said means being opelatively related to the main operating or. drive shaft ,4, whereby as hereinafter more fully-set forth the needle carriage and the warp supports or carriages are positively and preferably difi'erentially traversed through the machine byv means of Operating onnections from the said main drive shaft 4. i r

In the usual manner, the drawing needle 2 places successive warp threads through the desired heddle eye, selected reed dent and drop wires, these being appropriately positioned for the purpose 'in the needle path by suitable selecting and positioning mechanism. 1

The drawin -i n needle 2 may be operated in any suitab e manner. In order to opcrate the same and the other. portions of the mechanism, I have herein provided the main operating or drive shaft 4, which, as shown most clearly in Fig. 3, is provided with a driving pulley 5 receiving power from any suitable source. The said shaft is herein show-n as provided with 'a clutch 6 and a brake 7. As shown most clearly in Fig. 1, the shaft 4 is provided upon its lefthand end with a sprocket gear Sabout which passes a. sprocket chain 9 also passing abbut a sprocket ar 10 upon a shaft 11 having thereon ch..nge gear. mechanism diagrammatically indicated at 12 and conveying motion to a short shaft 13. The shaft 13 is provided with a sprocket gear 14 about which passes a sprocket chain 15 also passing about a sprocket pinion 15 on a shaft 16, whcih in the disclosed embodiment of my invention is provided with two distinct and separate cams 1'7, 18, most clearly indicatcd in Fig. 8, and which may be relatively positioned as desired and of different extent and contour, thereby to effect the independent control of the warp supports or earriages hereinafter referred to and at different rates of speed if desired.

The needle carriage 3 hereinbefore referred to as positively traversed through the machine is herein provided for that purpose with a divided nut 18 indicated in Fig. 4 and adapted to be placed through manual control or otherwise in suitable relation with a. thread 18" upon the cam shaft 16,

which thus constitutes a lead screw shaft be provided.

;28, 1921), wherein, however, but a single warp supporting means was provided, for the single warp there disclosed.

The needle 2 may be operated in any suitable manner. As herein "shown it is actuated from the main operating or drive shaft 4 through gearing indicated at'19 in Fig. 4 meshing with a. gear splined and slidable on the mam drive shaft 4, whereby is rotated the shaft 20 mounted upon the needle carriage and having thereon a crank wheel 21 connected by rod 22 with a lever arm 23, the lower end whereof is fulcrumed upon the needle carriage 3 and the upper end whereof is connected'by alink 24 to the holder for the heedle 2, whereby it is recipocated in the suitable guide' 'provided therefor. If desired and preferably I provide a needle stripper indicated generally at 25 in F ig. 4 and suitably operated from the shaft 20 through a shaft "26, bevel gearing 27 and tail.

The separate banks or groups of drop wires are supported or threaded upon lon-' gitudinally extending bars 28 shown' in Fig. 4 as three in number. Any suitable number of drop wire supporting bars may They may be loon'rbars or special bars onto which the drop wires are transferred from the loo-m bars. I provide suitable releasing means for said drop Wires and for that purpose have indicated in Fig. 4 shafts 29 provided with drop wire feeding worms 30, preferably of the general construction disclosed in the said ap lication of La Chance & Pennell (now atent No. 1,317,024). While the said shafts 29 may be the broad purpose and scope of my invention are concerned, I preferably impart a movement of continuous rotation to each of said shaftsjnstead of as heretofore intermittently rotating them and controlling such intermittent rotation through a pattern mechanism. For that purpose I have diagranunat'cally indicated in Fig. 4 a gear ing box 30 wherein are suitably mounted gears for rotating said shafts 29. Move ment of continuous rotation is imparted to the gearing insaid box by a gear 31 upon a shaft 32 indicated in Figs. 4 and 5, said shaft being driven through gearing hereinafter described In order to release-the dro) wires upon the bars 28, I preferably provi c rel ase key rods (not herein shown), the rotation whereof is controlled by suitable pattern mechalivered to the worms 30.

nism, The release key rods extend through openings in the drop wires in the general manner disclosed in the said patent to Lea, -No. 1,153,869, whereby at suitable times dropwires are released and are de- The pattern mechanism is diagrammatically indicated at 33 in Fig. 5, and is so constructed and arranged that the release key rods may be operated in any combination or sequence or variable order that is desired, thereby to release drop wires from any bar 28, to the feeding action of the feed worms 30. For example, the said shafts and the warp worm shafts hereinafter described and which are also controlled by the pattern mechanism, may be operated in a repeated sequence to present warp threads and drop wires to the needle or a plurality of threads may be presented by one worm shaft followed by the presentation of a plurality of threads by another worm shaft, or the said worm shafts, or any twoof them, may be operated simultaneously to present threads to the needle so that two warp threads would be drawn in at the same time. The feeding of warp threads from each warp support or carriage is independent of the feeding of warp threads from the other warp support or carriage, and the same is true of the releasing of the drop wires as well as of the heddles, hereinafter referred to.

In the disclosed embodiment of the invention, I. provide a plurality and herein specifically a pair of independent warp supporting means or carriages which are independently traversed through the machine. I etl'ect the independent automatic control of the said two warp supports'or carriages and I preferably also provide for the hand control of either of said carriages and, as herein disclosed, in a selective manner, and as above stated 1 provide for the pattern control of the individual warp threads of the said carriages. These purposes and objects of my invention may be effected in many different ways. I shall without in any way limiting myself thereto proceed to describe the selected embodiment of means 'for effecting the desired result.

Referring more particularly to Figs. 1 and 6, I have herein represented two war beams 34. 35, the. warp threads 36 from the beam 34 iassing through a suitable two-part clamp 3i mounted for sliding movement longitudinally of the machine in two bifurcated guides 38 provided in suitable brackets 39, one at each end of the machine and supported upon the end uprights of the fram- 3 mg. The warp threads 36 extend from the clamp 37 to and about a Warp worm 40 and thence to a second two-part'clamp 41. The warp worm 40 is suitably and herein loosely supported at the left hand end of the machine in a bracket 42 as indicated in Figs. 1

and 4, and at the. opposite end of the machine is suitably supported for rotative movement imparted thereto in any suitable manner. corresponding warp worm for the .warp threads supported upon the second warp carriage constitute separating, selecting and feeding mechanism for the individual warp threads. Preferably each warp worm comprises a frusto-conical, fluted portion, which first receives. disentangles and separates the warp threads, and a selective feeding or spacing screw or worm portion by which the threads'arc presented to the hook of the drawing-in needle 2 successively.

The warp threads 35 from the second warp beam 35 pass through the suitable twopart clamp 43 mounted similarly to the clamp37, in bifurcated guides 4-4 provided in said brackets 39 at opposite ends of the machine. The said warp threads 42 thence pass about the warp worm 45 supported in general parallel relation to the warpworm and driven in a suitable manner, and from thence said warp threads pass through a two-part clamp 46, said two warp worms 40, being within convenient range of the drawing-in needle.

The two warp worms 4U, 45 are each intermittentlydriven from the main drive shaft 4 and the intermittent driving thereof is controlled by pattern mechanism 33 (Fig. 5) whereby said worms. 4-0. 4-5 are independently rotated. Thus in the disclosed embodiment of my invention I selectively drive through the pattern mechanism the warp worms 40 and 45 and the key releasing shafts for the drop wires, and in addition I also so drive through the control of the pattern mechanism the hcddlc selecting elements, as hereinafter set. forth.

In the disclosed embodiment of the invention which is adapted to operate upon two warps, I'have provided an independent support or carriage mechanism for each warp. Herein the Warp clamps 37 and 41 constitute the support or carriage mechanism for one Warp and the clamps 43 and 46 constitute the support or carriage mechanism for the other warp, although the clamps of each support are structurally distinct. Any suitable means may be provided whereby independently and if desired differentially with respect to each other and (or) with respect to the traverse of the needle carriage, 1

the two pairs of clamps, that is, the two supports or carriage mechanisms may be traversed along the machine. Preferably, however, I have provided, as previously stated, the two cams 17, 18 upon the lead screw cam shaft 16. 'If desired, said cams may be of any desired extent, contour and shape to effect a, differentiation in speed of the feed of the two warp supports or carriages with respect to each other.

The said warp worm 40 and the 5 compensating movement which is in the nature of a movement continuously counteracting momentary variations in thread spacing. I therefore. as herein disclosed, provide a dilferential movement which is pref- 0 erably automatic and also provide a compensatingmovement which is preferably" a manual one. i

In "orderto ctbnvey motion from the said cams 1'7, 18 to the said two carriage mechanisms, I have herein'provided the following co-acting instrumentalities, to which, however, my invention is in no wise limited.

Upon'a stud 47, shown most clearly in i Figs. 7 and 8, are independently pivoted 2 two levers 48, 49, either or both of which cams 17, 18 by slotted ends of said levers 48, 49 are Ml-- mounted upon said worms 62,

may be held out of action by latches, one of which is indicatedat 49 in Fig. 7. Theselevers are'provided with projections 49 which are adapted to be held against the springs 49". To the upper justably secured links or rods 50, 51, the outer ends (it which are pivotally connected at 52, 53 (Fig. 6) to levers 54, 55, rigidly pins 56, 57, each pivoted in a second arm 58, 59. pivotally mounted upon stud 60, 61 extending from the framing. -Thes'e studs have loosely mounted thereon worms 62, 63, carrying or having integral therewith ratchets 64, 65 which are engaged by dogs or pawls 66, 67, fixed upon said pins 56, 57, whereby in the rotation of the said screw shaft 16, the cams 17, 18 impart ititrmittent and independent rotation'to the The means for imparting rotative move ment to each of said worms 62. 63 may be and preferably is similar to or the same as the means disclosed in the said application of Field,Lanning, Hathaway and Blan chard, Serial No. 142,251, (now Patent No. 1,383,195) for imparting rotatire movement to the worm disclosed therein, whereby the single warp carriage or support is traversed through the machine.

In order to transmit motion to the clamps 37, 43, from the said worms 62, 63, I have provided each of said clamps with a rack 68, 69 formed upon or attached to the inner face thereof and with the teeth of which said worms 62, 63 respectively mesh, whereby said clamps are independently and it' desired differentially with respect to each other and (or) with respect to the, needle carriage traversed along the-machine, in an automatic manner.

In order that the corresponding clamps 41, 46 constituting portions of said warp carriages, may be traversed along the machine, each in unison with its correspond- "the said chains 83, 84 also sprocket gears 97, 98, each carried by a suitin clamp 37, 43, I may provide any suitab e means. Herein I have mounted each of said clamps 41, 46 in the generally U- shaped brackets 70, 71. As shown most clearly in Fig. 9, each of said brackets has formed or mounted upon the lower face thereof a rack 72, with which mesh worms 74, loose upon stud shafts 76, 77 laterally extending from block 78, 78, mounted for longitudinal sliding movement upon the rods 80, 81 pivotally mounted at, 82 in the end brackets 39, it being understood that preferably at each end of the machine, I provide the described means supportin the said clamps 41, 46, the driving means t ere: for being, however, provided only'at one end of the machine. The said rods 80, 81 may be adjusted to any desired angle or inclination in their pivotal supports and clamped in the desired position to secure the proper tensioning and positioning of the warp threads.

In order to convey unison movement to clamps37, 41 and clamps 43, 46,'I may provide any suitable means, but herein I have shown two endless sprocket chains 83, 84, preferably provided at the left hand end of the machine, viewing Fig. 4, and passing about sprocket gears 85, 86, fast with the said worms 62, 63, and also passing about sprocket gears 87, 88 upon stud shafts 89, 90 mounted in suitable bearings su'pported upon a stationary shaft or support 91 extending from the frame upright at/t-he left hand end of the machine, as shown most clearly in Fig. l. Said sprocket cl1a i1'1s 83,84 also passahout idler sprocket pinions 92, 93, the former of which is mounted upon ,a suitale stud shaft 94 extending from the adjacent end bracket 39 and the latter of which is adjustablymounted upon the respective rod 80. Applicant is not limited to the construction or position of parts shown and here described, but has found sin-h eonstruction and positioning thereof to be convenient, effective, etc. baid sprocket chains 83, 84 mesh as shown with sprocket gears .95, 96, respectively fast with the worms 74, whereby the clamps 41, 4.6 are driven, the

extending about idler able block adjustably mounted upon the outer ends of said rods 80, 81, and also about suitable idler sprocket pinions 99. 100. mounted upon the adjacent bracket 39, and thus are returned to the respective sprocket gears 85, 86 upon the worms 62, (33.

In this or in any other suitable manner, unison movements are imparted to the clamp 37 and the clamp 41, constituting or comprising a portion of one warp carriage, and are alsoimpnrte'd to the clamps 43, 46, constituting or comprising a portion of the other Warp carriage.

In the disclosed embodiment-of my invention, the upper and lower clamps of the respective carriages are not mounted or held in a common housing or member, but they are operatively connected so as respectively to move together and thereby constitute portions of the respective warp supports or carriages.

Inadditionto the independent automatic control of the plurality of warp supports or carriages, 1 preferably provide for a selective hand control of either of said warp supports or carriages. and preferably whereby such hand control may be exercised first upon one and then upon the other of said warp supports or carriages, or in any desired order. I 1 I For this purpbse l have herein represented as pivotally mounted at 101 at each end of the machine upon the frame upright a. lever arm 102, herein represented as having pivotally connected thereto interme diate its ends a link 103 pivotally connected at its upper end at 104 to a lever arm 105 itself pivoted at 106. thereby providinr parallel motion means to effect and secure the proper movement of said lever arms 102. The outer free end of each lever arm 102 is provided with a transverse slot 107 having loosely mounted therein a shaft 108 having splined thereon a pinion 109 (Fig. 6) adapted to mesh with either a pinion 110 fast with the sprocket'87 or with a pinion 111 fast with the sprocket 88, the construe tion bein such that the pinion 109 remains in mesh with whichever pinion-110 or .111 it is manually brought into engagement. The pinion 1.09 is, as stated, splined upon the shaft 108 whereby said pinion may remain in mesh with either the pinion 110 or the pinion 111 while permitting longitudinal movementof said shaft 108, preferably manually, thereby to control the clutch mechanism of the machine in a manner similar to that disclosed in the patent 'to Hathaway andLea. No. 1,169,087, dated January 18, 1916. In this manner the machine may be stopped or started by the operator wherever he may be standing between the ends thereof. I have herein represented the said shaft 108 in Fig. 3, which is preferably formed as a tubing and having a plug swi'velled therein and bifurcated or vertically slotted at 112 as in the patent to Hathaway and Lea, No. 1,188,070, June 20, 1916. for the passage,as' indicated in dotted lines, of the upper'curved portion 113 of the upright lever 114 pivoted at 115 and operatively connected in a manner not herein necessary more fully to describe with the clutch 6 of the machine.

When it is not desired to impart hand adjustment to either warp'support or carriage, the shaft 108 may be swung into an elevated or non-active position by a movement of the lever arms 102 upwardly, the latter being then supported in such mm active position by any suitable latch or other means not herein shown and not herein necessary more fully to describe but phich may be similar to the latch 49' in 1. may, if desired, provide means manually to drive the main drive shaft 4 and the y'arious parts controlled thereby. For this purpose and as shown most clearlyin Figs. 1. 2 and 3, I have provided a longitudinally extending shaft- 116 mounted in suitable bearings 117, 117 and having if desired one or more hand wheels 118 to effect more ready rotative movement of said shaft. If desired, clutch or other means 118 (Fig. 2) may be provided to prevent rotation of the shaft 116 in the'wrong direction. At the left hand end of said shaft 1 have provided a bevel gear 119 meshing with a similar gear 120 upon an inclined shaft 121 extending in a downward direction into proximity to the main drive shaft 4, where similar beveled gears (not herein shown) are provided operatively to connect said shafts. By disconnecting the main power drive, the entire machine may be driven manually through the said shaft 116.

The machine herein disclosed may be and preferably is provided with means whereby the desired heddles of the various groups of heddles maybe selected and positioned for the passage therethrough of the drawing-in needle. In Fig. 4, I have indicated six heddle selecting shafts 122 each provided with a worm 123 of the general construction shown in the patent to Lea, No. 1.153.869, and in that to Millard F. Field, No. 755,861, the said worms and their shafts being controlled in operation by the pattern mechanism already described.

I t is evident that one of the warp beams 34. may carry the bulk of the warp threads and the other may carry a smaller I ing a woven-in stripe effect. The threads on one beam may be of a different size from those on the other or of a. different character, or they may be differentiated therefrom in any desired manner.

The bars 28, as previously stated, may be loom bars whereon in the weaving operation the drop wires are supported, or they may be special bars to which for the drawing-in operation the drop Wires are transferred. The said bars 28 are. preferably supported at one en in a clamp 122 indicated in Fig. 4, the other ends of said bars being preferably loosely supported in a suitable bracket 122 (F ig. 2) on the gear box 30. I preferthe drop wire feed norms The said carriage is s'lidable along a suitable track or support 124 (Fig. 2), not herein necessary more fully to describe.

It will be evident from the foregoing de scription that for each of the two sets of warp threads, I have provided two clamps, the clamps for each set of warp threads being automatically traversed longitudinally of the machine and the two sets of clamps for the two sets of warp threads being if desired traversed longitudinally of the machineat different rates of speed. Selective hand traversing means is provided whereby in any desired order the ,two sets of warp threads may be moved longitudinall of the machine to effect -compensation. i elective mechanism is provided governing the presenta'tion of the threads to the drawing-in needle, two separate warp worms being provided about which the respective warp threads are wrapped. Inasmuch as said warp worms are pattern controlled, it is evident that the threads may be fed to the action of thejftl'rawing-in needle in any desired order or sequence. By the pattern mechanism not only are the warp worms selectively controlled, but also the release key shafts 32' and the heddle worms 123, thus permitting any desired selection and drawing-in of the heddles, the drop wires and the warp threads.

In the disclosed embodiment of my inveution, I have in Figs; 10 and 11 represented six heddle manipulating rods 122 each pro vided with a worm. The number of these rods, of course, may be varied in different machines.

Y the call of the pattern mechanism. In Figs.

10 and 11, I have represented the reed opener shaft 126. this being also rotated in accordanpe with the call of the pattern in a manner not. here-1n necessary more fully to each of the drop wire feed worm rods pinions connected in rotation. The rod whereon is mounted one of said pinions extends through .the gear box 30' and has fast upon its outer end a pinion that meshes with the spur gear 31 on the shaft 32. As most.

Each of said rods is rotated ata short shaft 'mounted in the gear head.-

The shaft 135, as most clearlyshown in Fig. 11 has thereon a gear 137 meshing with a pinion 138 upon a shaft 139 having thereon 'a gear 140 meshing with a larger gear 141 upon a shaft 142. with a pinion 143 splined upon the main drive shaft 4 of the machine. It will there fore be evident from the foregoing description that the feed worms for the drop wires are constantly rotated from the main drive shaft of the machine. 1

The gear 141 on the shaft 142 meshes with a. gear 144'fast upon a shaft 145 as most he said gear 141 meshes clearlyshown in Fig. 11, and said gear 144 meshes with and drives a pinion 146 upon a shaft 147. By reason of. the Geneva like stop motion 148, 149,,the gear 150 upon the shaft 151 is intermittently rotated. Said gear 150 meshes with and intermittently rot-ates a' pinion upon the reed opener snaft126, but as indicated in Fig. 10 the rota-tion of said reed gear 1 56 upon a shaft 157, said gear 156' meshing with one of the pinions of the harness rods. The rotation of said harness rods is, however. subject to the call of the pattern as heretofore stated.

As shown most clearly in Fig. 10, the transverse shaft 130 has thereon a spira1 gear 159. meshing with a similar and smaller gear 160 upon a. short shaft 161 extending longitudinally of the machine. Said shaft .161 istherefore' continuously rotated from the main drive shaft (if the machine through the said transverse shaft 130 and the described connection therefrom to the said main drive shaft. T pon said constantly rotated shaft 161, as shown most clearly in Fig. 11, is a pinion 162 meshing with a .gear 163, which meshes. with and drives the pinions 164. 165, upon the shafts 164', 165 of the warp worms 40, 45. The rotation of said warp wormshafts is, however; controlled by the call of the pattern.

As most clearly shown in Fig. 11, the gear head 132 is provided with a base 166 having depending flanges 167 with inwardly extending bars 168 taking under the flanges 169 upon the framing of the machine. The bars 168 are rigidly connected with said gear head and also with the needle carriage whereby the gear head and needle carriage move in unison and as one member through I the machine. The needle carriage carries -'the warp worms 40. anddfi with it in its travel in the usual or any suitable way. The gear box is connected in the well-known or any suitable manner to travel with the one of which meshes with the adjacent pinion 155. I

Thus from the foregoing descriptlon, It

will be evident that the rotation of the reed opener, the harness control rods, the release key rods and the warp worm rods or shafts is controlled by the call of the pattern.

The pattern mechanism may be of any suitable character. It is shown in greatest detail in Fig. 10.

The pattern mechanism need not be described in detail, inasmuch as in its pre ferred form, it is like or substantially like that sho'wnin the said co-pending application of La Chance and Pennell (now Patent No. 1,317,024), like that disclosed in the application of Charles Lea, Serial No. 692,- 468 (now Patent No. 1,417,078, dated May 23, 1922), and like that shown in the patent to Hathaway and Lea, No. 1,169,087, January 18, 1916.

It is sufiicient to state that the pinions shown in fig. 11 are adapted to be clutched to their shafts to rotate the latter at the times desired. Said clutches are controlled by spring pressed rods and a pattern mechanism. Said pattern mechanism is herein represented as comprising a cylinder having perforations adapted to be brought into registration with a row of feeler bars, each having an,intervening lolank or separating washer. lVith each retraction of the drawing-in needle, the clutches of the pattern mechanism are thrown into engagement to connect the driving devices of the worm shafts therewith, but are immediately re leased unless hcld bythe interposition of a washer in the path-of a plunger rod.
